ARTHUR: NEW SPECIES OF UREDINEAE 39 
The same situation was detected on the same day in a collection 
by C. F. Baker, from Fort Collins, Colorado, collected June 10, 
1894, from which he drew the conclusion: ‘‘ Apparently the condi- 
tion is, that uredinia occur, later being often occupied by telio- 
spores.” Two days afterward in studying the same specimen he 
notes, that ‘“‘separate uredinia occur, occupied only by uredinio- 
spores, found at the tips of the younger leaves.’’ On June 21, 
1916, he found pycnia associated with uredinia in a specimen of 
Ellis & Ev. Fungi Columb. 2187, from Kansas. The association 
of pycnia with uredinia in other collections has later been verified 
by persons working upon material in the Arthur Herbarium, 
especially by H. R. Rosen the year following. 
From the above showing the short cycle genus of ordinary 
Uromyces appearance, which was characterized in 1906 under the 
name Telospora, requires another name, and Teleutospora is there- 
fore here proposed, with Uromyces Rudbeckiae Arth. & Holw. on 
Rudbeckia laciniata, as the type. This with two other American 
species should now be written as follows: 
Teleutospora Rudbeckiae (Arth. & Holw.) Arth. & Bisby 
(Uromyces Rudbeckiae Arth. & Holw.; Arth. Bull. Iowa Agr. 
Coll. 1884: 154. 1885). 
Teleutospora Solidaginis (Niessl) Arth. & Bisby (Uromyces 
Solidaginis Niessl, Verh. Natur.-Ver. Briinn 10: 163. 1872) 
Teleutospora bauhiniicola Arth. & Bisby (Uromyces bauhinticola 
Arth. Bot. Gaz. 39: 389. 1905). 
MICROPUCCINIA Rostrup 
Some months ago Professor H. S. Jackson, while working with 
material in the Arthur Herbarium, discovered that the type species 
of the genus Dasyspora, D. foveolata Berk. & Curt., is not a short 
cycle form, as had been assumed, but possesses uredinia of a 
very remarkable appearance. This discovery will be duly set 
forth in a paper to be published by Professor Jackson after a time. 
Not long afterward he came across the genus Micropuccinia in 
Rostrup’s excellent treatise on plant diseases, published in 1902, 
being duly characterized on page 266, with a number of species 
appended, the first being Micropuccinia Ribis (DC.) Rostr. This 
genus, if interpreted to include also those short cycle forms that
